Curriculum Review Videos
- The College Board is creating Review videos taught by actual AP teachers, unfortunately not me! I will watch them and post the ones I feel are appropriate. I am grouping them by major topic and ordering them as we constructed our models. I am including both AP Physics 1 and AP Physics C Mechanics videos as they tend to focus on different approaches. The AP 1 videos use great demos and focus more on a conceptual and proportional thinking approach to the learning of physics, while the AP C Mechanics videos are much more math intensive. As it appears at last report that this year's test may be more lab based with less calculations than normal, these AP Physics 1 review videos are perfect.
Motion in 1 Dimension
Motion in 1 Dimension
- AP Physics 1: Kinematics and the Definition of Acceleration
- A nice review with a very demo heavy approach. Also, a good discussion of a type of AP Physics 1 problem that could very well show up on this year's AP Physics C test.
- AP Physics C Mechanics: Kinematics: Motion in 1D (Part 1)
- AP Physics C Mechanics: Kinematics: Motion in 1D (Part 2)
- This one uses the Calculus!
Dynamics - Newton's Laws
Dynamics - Newton's Laws
- AP Physics 1: Forces in Equilibrium
- A good review, including friction. However, you will notice some force diagrams that I would never draw. For example, I like to draw my components on the diagram with the original force drawn as well, while he draws only the components and then does the trig off to the side. Not really an issue, just a difference. However, you will notice him do something I consider weird when he draws a line, not an arrow, between the heads of his perpendicular components and then does the trig. Although the math works, this is NOT a vector diagram as the components are not drawn head-to-tail which is the graphical representation of vector addition.
- AP C Mechanics: Newton's Laws of Motion: 1st and 2nd Law (Part 1)
- A good, thorough discussion of both kinetic and especially static friction. Loved the animation that he uses to explain why static friction has a range of values up to µ(Normal Force).
- AP Physics 1: Two Body Problems
- A discussion of two object problems including modified and full Atwood's Machines. The instructor does a couple of things different than I might.
- He emphasizes an approach using two separate objects with separate free body diagrams. Since the objects move together, I tend to do these problems as a two object system using a single, system diagram. He doesn't draw system diagrams unfortunately. The more complex the situation, the more useful a system approach is. However, if you want or are given the tension in the string, then the two separate objects with two separate force diagrams approach is required.
- Rather than using a conventional coordinate system where right and up are positive, down and left are negative as we have, he calls the direction of the acceleration positive. Both work, you just have to be consistent throughout the problem.
- A discussion of two object problems including modified and full Atwood's Machines. The instructor does a couple of things different than I might.
- AP Physics C Mechanics: Newton's Laws of Motion: 3rd Law (really, multiple body problems)
- In this video, systems are discussed and used to solve problems with multiple bodies more easily, but unfortunately, no system force diagrams are used. Not sure why these AP teachers don't use system force diagrams. I promise they really exist, I didn't make them up!
- Also, defines positive as the direction of the acceleration. Nothing inherently wrong with this method. It works. It's just different from what we use.
Motion in 2&3 D - including Projectile Motion and Uniform Circular Motion
Motion in 2&3 D - including Projectile Motion and Uniform Circular Motion
- AP Physics 1: Projectile Motion
- A good review of all things projectile motion including advice on answering Qualitative/Quantitative Free Response problems which are typically an AP Physics 1 thing, but this year may also be part of the AP Physics c Mechanics test.
- AP Physics C Mechanics: Kinematics: Motion in 2D (Part 1)
- I really did not like this one. If you want to watch it, I cannot stop you, but I think there are better things to do with your time.
- AP Physics C Mechanics: Kinematics: Motion in 2D (Part 2)
- More useful, especially the discussion on types of questions on this year's AP C Mechanics test and some examples of such.
- AP Physics 1: Circular Motion
- This is a better review of Circular Motion than the AP C videos, just in more basic situations. Definitely watch this one first!
- AP Physics C Mechanics: Circular Motion (Part 1)
- It's a video. Includes several Circular Motion examples.
- AP Physics C Mechanics: Circular Motion (Part 2)
- Many examples of both uniform and non-unifom circular motion.
- Example at around 14 min. would not appear on this year's test. It's ok if those equations do not look familiar.
- Part A of the Free Response example at around 35 min. is much easier, IMHO, if you use energy conservation of the block, incline, Earth system.
Ei = EfEgi = Ekfmgh = 1/2 mv2h = v2 / 2g
Energy
Energy
- AP Physics 1: Energy Bar Charts
- In this video LOL diagrams are mentioned, but not completely used. He modifies the O. It's definitely close enough to be useful as a review.
- Pay close attention to the definition of system as much like in the Energy Concept Builders you did earlier in the year, different systems change whether or not there are external forces that do work. We tend to use inclusive system that lessen the need for work. Energy with less Work! (LOL)
- AP Physics 1: Problem-Solving with Energy
- Uses Energy Bar Charts to help set up the Energy Equations. Remember that Energy Bar Chartsare like our LOL Diagrams with a somewhat different O.
- In the very first example we would put the slide in the system as well and then it is an isolated system resulting in energy being conserved. Then we would have two bars of emery dissipated by friction in our final and NO work done at all. See, our approach is ENERGY WITH LESS WORK!
- AP Physics C Mechanics: Work-Energy Theorem
- We don't approach Energy from a particle standpoint. Instead we use systems. The more complete the system the better. Because of our more inclusive approach, I never taught you this theorem. There is no need, as our approach simplifies to this theorem if the circumstances demand it.
- Instead, we
- Define our system
- Decide if the system is isolated (no external forces)
- If isolated, Energy is conserved and ΔEint = 0
- If there are external forces, they do work and transfer energy into or out of our system. Hence,
W = ΔEint.- Then we decide which of our storage mechanisms change, and away we go. No need for special equations for special circumstances
- Because of this as well as because we have already done several of the examples covered in the video, I do not think this video is worthwhile for you.
- AP Physics C Mechanics: Conservation of Energy (Part 1)
- This one is even more muddled than the one above, I suggest you skip it.
- AP Physics C Mechanics: Conservation of Energy (Part 2)
- More or less watchable although often not written out in the manner I would prefer. Definitely watch the AP 1 video first!
- In the very first example, besides the possibility mentioned that perhaps the ball was released lower than ideal, a second answer might be that air resistance dissipates some energy resulting in less kinetic energy at the bottom and therefore a slower speed than predicted. Notice that my answer is written as you should on an AP test with a complete explanation.
- AP Physics C Mechanics: Forces and Potential Energy
- This video reviews potential energy as a function of position, including the Calculus and a ton of graphing work. A good one to watch!
- At one point there was a several minute blackout during the live presentation, just forward through it.
- AP Physics C Mechanics: Power
- Good Review of Power, including from a Calculus perspective. Some good AP C 2020 like examples.
Impulse and Momuntum
Impulse and Momuntum
- AP Physics 1: Conservation of Linear Momentum
- A thorough discussion of impulse, momentum, the impuse-change in momentum theorem, the conservation of momentum, and even a little center of mass.
- AP Physics C Mechanics - Center of Mass
- Not exactly the way we developed the ideas, but it gets there. As usual, some good animations.
- AP Physics C Mechanics - Impulse & Momentum
- A review of both with some calculus and examples.
- AP Physics C Mechanics - Conservation of Linear Momentum (Part 1)
- The problems from Physics Classroom mentioned are already on the AP C Review Problems page of this website.
- AP Physics C Mechanics - Conservation of Linear Momentum, Collisions (Part 2)
- There is four (4) minutes of music before the video actually begins.
- This one is interesting as he uses a completely different approach to solve elastic collision problems, the center of mass frame of reference. We always used the Earth frame of reference. Both work!
- On January 8-9 we derived two big equations that describe one dimensional elastic collisions and then employed them to guide our predictions and calculate final velocities. You could review those videos if desired. In specific cases like one of the examples where the masses are integer multiples and one object starts at rest, the two equations could be used, or you can derive this special case with relatively little algebra. Since this year's test is open book, I would suggest you add these two equations to your equation sheet.
- Watch this one to the very end as he talks about a method for answering lab procedure AP questions he calls SQUARED that may be useful.
Rotation
Rotation
- AP Physics 1: Rotational Kinematics
- This video is an AP Physics 1 treatment of Rotational Kinematics. He only uses Kinematic Equations 1, 3-4. I did like how he explained what we have called proportional thinking.
- AP Physics 1: Connecting Angular and Linear Speed
- AP Physics C Mechanics - Rotational Kinematics
- Unfortunately, this one is a lot of examples, many of which are more involved than just Rotational Kinematics. I would suggest watching the AP Physics 1 videos.
- AP Physics 1: Torque in Equilibrium
- This is a nice review of basic Torque and Static Equilibrium.
- AP Physics 1: Experimental Design: Torque in Equilibrium
- Another AP Physics 1 video. This one does a good job of explaining how to handle the lab based Free Response problem. Note the use of linearization, the line of best fit and the use of its SLOPE to calculate an answer. Also, a good review of various ways to measure Force experimentally.
- AP Physics C Mechanics - Torque and Rotational Statics (part 1)
- This video is completely misnamed as it is all about ROTATIONAL INERTIA.
- It reviews the basics, derives the rotational inertia of a thin rod about the center of mass using the Calculus and even explains and then uses the Parallel-Axis Theorem.
- In the derivation of the rotational inertia of a thin rod about the center or mass, he uses an unconventional approach to handle the change of variable required. You can always go back and look at your notes or at the PowerPoint from Monday, February 27 called Rotational Inertia of Continuous Objects.
- When using the Parallel-Axis Theorem, notice that we use the more commonly used symbol h for the distance from the center of mass to the parallel axis.
- AP Physics C Mechanics - Torque and Rotational Statics (Part 2)
- Unfortunately, there is no review of basic ideas, instead it's a bunch of examples.
- If you want to go through a bunch of examples, watch this video, but if instead you are looking for more of a review I would suggest the AP Physics 1 video Torque in Equilibrium above.
- AP Physics 1: Rotation - Newton's 2nd Law
- Be sure to pay attention to the different ways he measures angular velocity.
- AP Physics C Mechanics - Rotational Dynamics and Energy (Part 1)
- This is all about Rotational Dynamics, no energy.
- A good review of basic principles in a manner more consistent with this year's test.
- Watch this one!
- AP Physics 1: Rotational Kinetic Energy
- AP Physics C Mechanics - Rotational Dynamics and Energy (Part 2)
- After the opening example, this video is all about energy.
- A good review of rotational kinetic energy and of applications of the Conservation of Energy including perfect rolling and even a little rolling with slipping.
- Examples are focused on this year's test.
- AP Physics 1: Conservation of Angular Momentum
- AP Physics C Mechanics - Angular Momentum and its Conservation
- Not a lot of review, mostly just a bunch of examples, some of which we have already done. I would suggest watching the AP Physics 1 video on Angular Momentum above rather than this one.
